DUST-CAP son rmnvnnvns'.

To all whom t concern:

Be it known that I, ROBERT H. HENEMIER,

`n citizenof the United Stutesof America,

residing in the borough of Manhattan, city, county, and State o New York, have invented certein new und useful ,Improve5 ments 1n Dustsips forI Tue-Valves, of`

structed in such mnnnerthut either or both may be quickly attached or detached.. This permits the quick application of a` pump coupling, when it is desired to infiete the tire,

and the quick detachment of the major portion of the structure when it is desired to remove the tire from the Wheel rim. Pref* erobly the detachment of the valve. oep portion permits the removal lof the dent cup portion by a sliding movement, and the up plicetion of the vulve cup portion secures lthe dust cup portion in places The invention includes other features and improvements Awhich will be hereinafter more 'fully described.

Referring tothe drawings which illustrate several` forms of the invention :f-

Figurel is an elevation of the cop es ftp-- plied. to n tire valve, the vulve cop portion being shown detached;

Figa@ is :rdiametriciil section loi the 'device, :i port of the vaive oop portion being shown in elevation; and

Fig. 3 is :i similar section ot n modified form. n

Referring first to Figs. 1 and 2, leti' indiente :i Standard form. of vulve, havingr :i nipple B of reduced diameter, adopted to receive :i pump coupling or vulve cup. h

C indicates the dust cup ns :i whole, which comprises e dust cop portion D und :i vulve cop portion E. The dust'cnp portion l'l is preferably constructed with n cylindrical member adopted to slide down over the threads of the vulve body, the upper end oi the dust cup portion having :i hole or pusszige through which the volvo nipple extends when the dust cop portion is in place. Means nre preferably provided to .heid the dust cup portion in 'its adjusted position by friction', which should :it leest be suflicient specification of Leners Patent.

dust or moisture ut the bottom of the cup,

tho cork having the capacity', to some extent,

ot' swelling soi that it whoiiy or partially lls the threads vou the exterior oif the "vulve cz'isingil und. `to :i considerable extent, fills np the space left by the fiets on 'the valve. An internal ilunge h" may he provided to pre1 vent the cork lining from puiliog ont of the structure. Preferably, the dust oep portion is so formed that there le'it u iiunge (gi et its top, which engages the usuari shouider on the vnlve casing het-Ween the body portion und the nipple 15, thereby l'limiting,r the onv Ward movement of the dust cop portion.

The valve cup portion, which is .lettered E, in port muy be formed ot' the standard vulve cup, the internal construction being;r any that muy besnitubie 'for the purpose oi seniing the outer end ot the vulve. The body of such cop is iettered H in the drawing. It Curries, or is :formed with n shirt portion J, which extendsdowniinrdly ontil it either contncts with the top ol the duet rep portion tl to D, or is in o. close proniniito The sli" ft portion J' servos to pn :he 'threads oi yhe nipple and prevent il ,.i `es of dirt und. dust, :ind also serres to chimp the dust cap pol-pion .D in pince, so that its lengthwise reino :il is impo' ile, so linie; as the vulve cop portion is in position on the Volvo nipple.

By the constructifni thus described, ull of the threads of thc unive cui no; ure protected. including that oi the nipple Ti. At the Isome time, the vulve is eusily :iccessible for purposes` of inilutioo, und the entire structure muy be removed or epplimiv without e long` screwing operation.

The construction ot Figs. i. :ind 2 best adopted tor wives boring u stenduf'd or unitornrdeizrfni ot projection 'from the wheel folly. To nccomn'mdotc those vulvoswhich have :in indetoi-minute degree oi projection, l prefer the construction ot Fig. -l. wherein the dust cup portion is formed, in two parts,

D and Dzfteleseoically connected, so that when the Sect-ion' is in oontactwith the shoulder 0fthe valve easing, the section D2 .may beadjusted* downwardly until it meets the wheel telly. r-The connection between the two may' he' either a sliding connection or a vvscrew-threaded connection, as is Shown.

While l haveshown and described several Vemhodiments of theinvention, it is to. be understood that I donotwish to be limited thereto, since various chaudes may he made therein Without. departing from the spirit of* portion being adapted to slide own over the valve easing and having a passage formed therein for the valve, and the valve cap portion. being adapted to screw on the valve to hold the'ciust cap portion in place.

' g essere? 2. A dust cap comprising n lust cup por tion and a valve cap portion, the dust carp portion beingr adapted to slide down over the valve casing and having :t passage formed therein for the valve nipple, and the valve cap portion being adapted to screw on the valve nipple, and having :i Skirt portion adapted to Contact with the dust cup portion to hold the latter in place.

v 3. A dust cup having :i dust cup portion and a vulve cap portion, the (inst cup portion being adapted toslide along the vulve cusing and being formed in two. parte telescopiozilly connected, und the vulve up portion being adapted to engage the valve'nipple and engaging' the end of the dust cup portion to hold the lutter in place.

In witness whereof, l. have hereunto signed my name.
